The Final Four has a home team, three power-conference heavyweights, two of the nation’s top coaches and its most revered program.

There are story lines aplenty this weekend in Indianapolis. But what the four teams taking the court today don’t have is elite talent.

The No. 1 pick in the upcoming NBA draft won’t be on display.

Nor will the No. 2 . . . or the No. 10.

There are no Carmelo Anthonys, Greg Odens or Derrick Roses. There isn’t even a Tyler Hansbrough.

But the least-talented Final Four in ages is also the most wide open in years. Duke is the only No. 1 seed and the favorite. But any of the teams could win the championship, making this a fitting conclusion to what has been a wild, captivating tournament.

What should we expect, both on the court and off? It starts with . . .

Defense: What the Final Four lacks in high-octane offense, it makes up for in ferocious man-to-man defense.

In their 16 tournament games to date, Duke, West Virginia, Butler and Michigan State have allowed 70 points or more only twice.

Duke and West Virginia might climb into the 60s today. But Michigan State and Butler are liable to play the lowest-scoring Final Four game since the Spartans’ notorious 53-41 victory over Wisconsin in 2000.

Butler Blue II: The Butler mascot could be the Final Four’s biggest star. He’s a 6-year-old, 60-pound English bulldog with his own blog and more than 1,000 followers on Twitter.

At Butler home games, Blue II roams the arena while fans pet him. This week, he was taken to an Indianapolis spa for pre-Final Four grooming. (Reportedly, he was not happy about being blow-dried.)

Chances are, you won’t see Blue II without his oversized bone.

“The Masters” promotions: How many shots of immaculately groomed fairways, Rae’s Creek and Tiger Woods — all with Jim Nantz voice-overs, of course — will we see?

Figuring that CBS will show four per hour during its nine-plus hours of coverage, the guess here is 37.

Big Shot Butler: Which player is most likely to deliver a game-winner? That would be West Virginia guard Da’Sean Butler, who has already made six buzzer-beaters this season, including two in the Big East tournament.

His big-shot counterpart at Butler is versatile forward Gordon Hayward, while guard Nolan Smith was Duke’s go-to scorer in the Elite Eight.

Several players have produced big baskets for Michigan State, including wing Durrell Summers and point guard Korie Lucious, whose 3-pointer beat Maryland in the second round.

Faces in the crowd: We’ll get plenty of shots of Magic Johnson in the Michigan State cheering section, and the CBS cameras will no doubt find an anxious Mickie Krzyzewski behind the Duke bench.

When Butler is playing, we might see Bobby Plump, the former Milan High star who was the model for the Jimmy Chitwood character in “Hoosiers.”

But West Virginia legend Jerry West is not expected to attend even though his son, Jonnie, plays for the Mountaineers.

“I don’t want to be a distraction,” West told the Charleston Daily Mail. “His mother will be there. For me, I would rather take a little bit different approach to games and do what works so far — keep away.”

Semifinal I winner: How will Butler react to the moment — to playing in the Final Four for the first time (and doing it at home)? If the Bulldogs shoot well from the perimeter, Michigan State will have a difficult time keeping pace.

But it’s more likely that the physical Spartans will wear down Butler’s big men and squeeze the life out of the Bulldogs down the stretch, one rugged possession at a time.

Semifinal II winner: West Virginia won’t score as easily as it did against Kentucky, and Duke won’t rebound as easily as it did against Baylor.

The outcome will hinge on which team is better able to score against a locked-in half-court defense in the pressure-packed final minutes. In that difficult, desperate situation, Duke has more options with Smith, Kyle Singler and Jon Scheyer.

Championship pick: Another grinder, just the way Michigan State coach Tom Izzo likes ’em.

With its granite defense and a half-court attack that’s as efficient as it needs to be, the Spartans power to their third national title (and second under Izzo).

But know this: Whether the last team standing is Michigan State or Duke, Butler or West Virginia, it won’t be confused with the best teams of the past decade.
